PIE TRIMMING AND BIlVl'l/.E-ING MACHINE.

` Application filed August 7, 1924. Serial No. 730,598.

T0 f/.ZZ Lo/tom 'it may concern:

Be it known thatI, GEORGE N. CoNDYLns. a citizen of the Greek Republic, residing at Richmond, in the county of Henrico, State of Virginimhave invented new and useful improvements in Pie Trimming and Riinming Machines, of which the following is a specification.

This invention relates to and rimming` machine. l

rlhe object of the present invention is to provide a simple, practical andV efficient pie trimmingand rimming machine of strong and durable construction adapted to enable pies to be easily and rapidly trimmed and rimmed.

A further object of the invention'is to providea machine of this character which will not be limited to pie platesof a given diameter but which will be capable of rimming and trimming the dough of pie plates of different sizes.

It is also an object of the invention to provide a pie trimming and rimming machine adapted to trim and rim the bottom crust of open pies where the fruit or other material is placed in the lower crust after the same has been rimmed and trimmed and capable also of enabling pies having a top crust to be properly trimmed.

It is also an objectof the invention to provide a pie trimming and rimming machine adapted to have the pie supporting means duplicated in order that a plurality of persons may simultaneously use the machine.

Vith these and other objects in view, the invention consists in the construction and novel combination and arrangement of parts hereinafter fully described, illustrated in the accompanying drawings and pointed out in the claims hereto appended, it being understood that various changes in the form, proportion and minor details of construction, within the scope of the claims, may be resorted to without departing from the spirit or sacrificing any of the advantages ofthe invention.

In the drawings:

v4Figure 5 is a plan View of the same,

In the accompanying drawings in which is illustrated the preferred embodiment of the invention, the pie trimming` and rimming machine comprises in its construction, a

supported in any deepening 2 for the reception of a rotary pie plate support 3 preferably consisting of a disk, as clearly illustrated. in Fig. 2 of the drawings. The rotary pie plate support which is arranged in Hush relation with `the upper face of the table 1 is provided at the lower face with a depending central hub portion 4: having a socket 5 for the reception of the upper end of the shaft 6 to which the hub is secured by means of a set screwV 7 but any other suitable means may of course be employed for fixing the hub of the rotary upper end of the shaft 6. The vertical shaft 6, which is rela- Atively short is journalled in acentral bearing` 7 of a bearing bracket 8 preferably consisting of a bar of metal having its terminals bent upwardly and forming approximately L-shaped arms 9, which are bolted or otherwise secured to the lower face of the table 1, as clearly shown in Fig. 1 of the drawings. The bearing across the circular opening 2, but of course il may be of any other desired construction as will be readily understood.

The rotary support 3v is adapted to receive a pie' plate 10 over which a sheetof dough is placed in the usual manner to form the bottom crust of pie, and the pie plate is then placed upon the support 3 as illustrated in FigA 1 of the drawing and is maintained in proper frictional engagement with the roy tary support 3 by means of a holder 11 consisting when designed for open pies, of a tapered or inverted trunco-conical body and provided with a central upwardly extending stem 12 on which is loosely pivoted a handle 13. The handle 13, which-may consist of a disk or be of any other desired form, is adapted to be grasped by the hand and it is pierced'by a central pivot 14. The op-` extending outwardlyA bracket depends below the table and extends erator by means of the holder is adapted to maintain the pie plate and its sheet of dough on the support 3 and is enabled to hold the pie plate in contact with a pair of shaping rollers 15, having inverted conical upper portions 16, which cooperate with the tapered holder 11 to form a substantially triangular s ace 17 above the rim of the pie plate and etween the holder and the shaping rollers for rinnning the dough and trimming the superfluous dough from the pie plate. The shaping rollers and the pie plate support are rotated by the gearing hereinafter described and the contigi'ious portions of thc rotary supportv and the rollers move in the same direction and when the pie plate with its sheet of dough is brought in Contact with the shaping rollers, the dough will be lifted by the rollers and crowded into the triangular space and rimmed in a triangular form in cross section upon the rim of the pie plate. The lower portion 18 of the shaping rollers may be tapered or conical as shown or the diameter and Ashape may be varied to construct the rollers to suit the different diameters of pie plates designed to be use-d in the machine. In one aspect of the invention, the upper and lower reversely arranged conical portions of the shaping device or rollers provide the latter with a peripheral groove or recess to receive the rim of the receptacles to operate on the dough carried on the rim of the receptacles. The engagement between the pie plate and the shaping rollers as the support is rotated causes the dough to be trimmed off while the rimmed dough is built up in the said triangular'V form upon the pie plate The pressure may be regulated by the operator grasping the handle 13 as will be readily understood. y

' The shaping rollers are mounted on vertical shafts 19 which are connected by bevelled gears 20 and 2.1 with a horizontal shaft 22and one of the vertical shafts 19 is connected by horizontal spur gears 23 and 24k with the central vertical shaft 6 for p0sitively rotating the pie plate support. The spur gear 24 is prefer-ably approximately the diameter of the rotary pie plate support while the meshing gear 23 is of substantially the diameter ofthe shaping roller, and vit will be clear that the veitical bevelled gears 2l, by meshing with the horizontal. bevelled gears 2O at the same side thereof will cause the shaping rollers to rotate in the .same direotion while the spur` gearing will cause a reverse rotation of the pie plate support, thereby producing movement of the adjacent portions of the pie plate support and the shaping roller-s in the some direction vfor shapingand trimming the dough.

The machine -may be drivenfby any suitable power and in the accompanying drawings, is yillustrated an electric motor 25 which .is meestal by Spill* sears 26 and 27 with `rectangular plates presenting the horizontal shaft 22. Any other form of gearing, however, may be employed and the gearing will in practice impart to the shaft 22, the desired speed of rotation.

The rotary pie plate support 3 may be duplicated by arranging an additional pie plate support at the opposite side of the shaping rollers 15. The gearing is the same as that heretofore described with the sole exception that the horizontal spur gearing is duplicated, one set of the gears 23 and 24. being connected with each of the vertical shafts 19 so that the rotary pie plate 'supn port 3 `at each side of the shaping rollers will be positively rotated in the same inanner as that heretofore described. This will enable two persons to operate the machine simultaneously one person working at one side of the table and another at the opposite` side and neither will interfere with the other.

Also when it is desired to trim pies having upper and lower orusts, a pie holder 28 of the form illustrated in Figs. 4 and `5 of the drawings is employed. The pie holder 28 is provided with a plurality of arms 29 arranged at an inclination and provided at their outer ends with horizontal engaging` portions 3() consisting of substantially flat lower faces'to the dough and spaced clear around the pie plate as clearly shown in Fig. 5. The arms 29 are three in number but the number may of course, be varied as will be readily understood and they are connected at their upper ends to a central hub 31, having a vertical pivot 32 on which is mounted a handle 38 consisting of a disk similar to the handle heretofore described. The pie plate holder is adapted to be placed upon the upper crust ofthe pie and it will enable the pie plate to be maintained upon the support and in frictional engagement with the same and with the shaping rollers for trimming the dough.

The shaping rollers are spaced apart a distance less than the diameter of the pie support and in the present machine it is not necessary that the -pie plate be of the same diameter as the space between the shaping rollers but on the contrary, the pie plates are of greater diameter than the space between the shaping rollers and pie plates of various sizes may be used in the machine with equal facility. machine, the sheet of dough is placed in the pie plate 4and `the hold-er l1 is placed within the pie plate upon to be an open pie which is filled after the trimming and rimming. The pie vplate with its sheet of dough and holder is then placed vupon the support and moved over the same to a position contiguous to the shaping rollers andit is held in such position until the rim ofthe lower crust is built up upon vIn the operation of the v the dough if the pie is the rim of the pie plate and the excess dough trimmed from the pie plate. The height of the rim is dependent on the size of the body 1l and the distance it projects above the pie plate in conjunction with the size and shape of the shaping rollers. This determines the size of the space 1T and the consequent size and shape of the built up rim' of the lower crust. The lower portion of the shaping roller picks up the hanging dough and lifts and feeds the same to the space 17 and the rotary movement of the shaping rollers and the pie plate rapidly and accurately rims and trims the dough and produces an artistic and uniform lower pie crust. The trimming of a pie having an upper crust is performed in a similar manner with the eX- ception that the pie holder illustrated in Figs. 4 and 5 is used. While the rotary pie supportis shown duplicated in F of the drawings, it will be readily understood that the shaping rollers and the rotary pie plate support may be duplicated to provide a machine for accommodating any desired number of operators. The horizontal shaft is hung from the table insuitable hangers 84 but may be mounted in any other desired manner.
